Jacket in light stretch nylon that, with a special weaving technique, automatically creates from the loom the compartments where the feather padding is then injected. Seams are thus avoided, with the advantage of substantially increasing the hold of the feather inside the chambers. The finished garment is padded via direct injection with the finest feathers, specifically treated to resist garment dyeing. The addition of a special agent to the dye recipe makes the garment anti-drop.
